I don't know if you saw, but IMO gave a second clue in reply to Arneb:

Yes ... second half of 20th century. Hint: sketches of Mercury were involved as were observations of stellar occultations by Mars. The physical characteristics involved were very different in the two cases.

So I took that to mean that the corrections could be from 1950 on. I liked my Antoniadi idea at first, because he too had Mercury's rotation wrong, but only Mariner 4 could conclusively show there were no seas on Mars as Schiaperelli thought. Antoniadi had already criticized Lowell.
IMO needs to get out of bed.
